sorry to hear about your troubles getting onto this thread, i wish i could be of more help, but the host i'm currently with doesn't give much information why users keep getting logged out. They simply recommend firefox, but u said u could get that. Maybe try to change your cookies settings to "Allow All", perhaps that'll fix this little issue.
As for garage band, i don't believe so, i've looked all over the web for it along with some other programs that are found on a mac that i wish i could have for my xp based computer. If i find anything i will definitely pass it on
